GEMS: Workshops

Next GEMS Workshop

📅 Pre-Goldschmidt conference (11-12 July 2026)

Ore-forming processes and metasomatism: experimental and modeling methods for interpreting critical mineral deposits in geologic systems. Workshop Registration Page.

The workshop is intended for graduate students, researchers, and professionals who want to learn how to apply the GEMS code package coupled to the MINES thermodynamic database and high P-T PHREEQC coupled with SUPCRTBL to geochemical modeling, as well as learn about how to use current experimental methods regarding fluid-rock equilibria to interpret the evolution of natural ore-forming systems at elevated P-T conditions. The workshop will cover: 1) fundamentals of the GEM-Selektor code package and PHREEQC and thermodynamic databases for simulating fluid-rock systems; 2) the GEMSFITS parameter optimization tool and ThermoFun for optimizing thermodynamic properties against experimental data; 3) an overview of experimental advances in the study of aqueous complexes and mineral solubilities in hydrothermal fluids; 4) the stability and mobility of metasomatically induced and altered REE mineral phases in crustal rocks (e.g. monazite, xenotime, apatite, allanite, and titanite); 5) insights from field case studies of critical mineral deposits.

📅 Past workshop 2025

We’re thrilled to look back on a successful Thermodynamic Modeling Workshop (June 3-6 2025) at Empa, where around 40 participants—from PhD students and postdocs to industry professionals—gained hands-on expertise in GEMS for cementitious materials ...read more
